Buying guide on black diamond jewelry

Black diamonds are not often used in jewelry when compared to white diamonds. But black diamond jewelry with its unusual appeal is more and more popular in fashion jewelry world. When you decide to buy black diamond jewelry, you have some basic knowledge to learn.
Just like white diamond, black diamond are also somewhat of a modern novelty item in jewelry design. Black diamonds are valued on carats, the clarity of the stone, the color and the cut as well.
Open your eyes to identify the natural diamond and treated black diamond. The natural diamonds are more valuable than treated ones. The diamond before treatment may have had flaws which are now less visible because of the black coloring.
Look at the metal of the jewelry piece, such as necklace, bracelet, earrings and wedding ring. It should be clearly marked if it's gold, silver or platinum. Sterling silver and vermeil are much less expensive than gold or platinum, and the price of the jewelry should reflect that.
Black diamonds are rare, but that rarity doesn't necessarily translate into higher prices than clear or colorless diamonds. Don't be misled by the salesperson or promotional materials.
